Wolfdale_(microprocessor)
Wolfdale is the code name for a processor from Intel that is sold in varying configurations as Core 2 Duo, Celeron, Pentium and Xeon. In Intel's Tick-Tock cycle, the 2007/2008 "Tick" was Penryn microarchitecture, the shrink of the Merom microarchitecture to 45 nanometers as CPUID model 23. This replaced the Conroe processor with Wolfdale.
The Wolfdale chips come in four sizes, with 6 MB and 3 MB L2 cache (Core 2 Duo); the smaller version is commonly called Wolfdale-3M, 2 MB L2 (Pentium), and 1 MB L2 (Celeron).
The mobile version of Wolfdale is Penryn and the dual-socket server version is Wolfdale-DP. The Yorkfield desktop processor is a quad-core Multi-chip module of Wolfdale.
